摘要：

Using a ray-tracing code,the imaging process of non-point light sources through a concave grating has been studied. It is demonstrated that under specially designed conditions,a plane spectrum can be formed for non-point light sources. The positions for the plane spectrum have been derived for the sources at different distance from the grating. A criterion has been defined under which the effects of variation of the source-size on the focal plane can be neglected.
